| 20090023057 | POUCH TYPE BATTERY PACK - A pouch type battery pack, including: a first pouch battery and a second pouch battery adjacent to the first pouch battery, wherein the first and second pouch batteries are combined by bonding an edge of the first pouch battery and an edge of the second pouch battery to each other. Accordingly, the bare cell can be separated without being damaged when the pouch battery is separated from the battery pack. Furthermore, the heat radiation performance is improved by including a heat radiation member between the two pouch batteries when the pouch batteries are stacked. | 01-22-2009 |
| 20090023058 | POUCH-TYPE SECONDARY BATTERY - A pouch-type secondary battery including: an electrode assembly having a first electrode plate, a second electrode plate, and a separator disposed therebetween; and a pouch case including a first case part having a pouch to house the electrode assembly, a second case part disposed over an open end of the pouch, and sealing portions to seal the second case part to the first case part. The sealing portions include wing portions that are bent to cover opposing sides of the pouch, and bent portions that are bent from the wing portions, to cover a bottom surface of the pouch. | 01-22-2009 |
| 20090023062 | POUCH TYPE LITHIUM SECONDARY BATTERY - A pouch type lithium secondary battery includes: an electrode assembly including electrode tabs respectively connected to two electrodes, the two electrodes having different polarities; and a case to house the electrode assembly such that the electrode tabs extend to the outside of the case, wherein one stepped part through which the two electrode tabs simultaneously extend is formed in a sealing portion of the case. In the electrode sealing portion of the pouch type lithium secondary battery having short width, sealing of the case is improved by the one stepped part, thereby improving efficiency of the manufacturing process of the battery. | 01-22-2009 |
| 20090029246 | Pouch-type secondary battery - A pouch-type secondary battery including: an electrode assembly including a positive electrode, a negative electrode, and a separator interposed therebetween; a pouch case housing the electrode assembly, having a sealing portion to seal at least at a part of the periphery of the pouch case; and a positive electrode tap and a negative electrode tap electrically connected to the positive electrode and the negative electrode, respectively. The electrode taps extend through the sealing portion, and out of the pouch case each. The secondary battery includes an insulator that covers at least portions of one or both of the electrode taps. The insulator can include hole that expose portions of the electrode taps. | 01-29-2009 |
| 20100035144 | ELECTRODE ASSEMBLY AND LITHIUM SECONDARY BATTERY USING THE SAME - An electrode assembly and a lithium secondary battery including the same. Heat generation of the electrode tabs is reduced by providing the electrode tabs at the outermost parts of the electrode assembly. An insulation member is attached at the boundary of the electrode tabs and the respective electrode plates. An insulation member is also attached to the uncoated portions formed on the outer circumference of the electrode assembly, thereby preventing internal short circuits either between an uncoated portion and an active material layer or between the uncoated portions. The electrode assembly can be used in pouch, rectangular and cylindrical lithium secondary batteries to prevent an internal short circuit within the batteries. | 02-11-2010 |
| 20110091764 | POUCH-TYPE SECONDARY BATTERY - A pouch-type secondary battery including: an electrode assembly having a first electrode plate, a second electrode plate, and a separator disposed therebetween; and a pouch case including a first case part having a pouch to house the electrode assembly, a second case part disposed over an open end of the pouch, and sealing portions to seal the second case part to the first case part. The sealing portions include wing portions that are bent to cover opposing sides of the pouch, and bent portions that are bent from the wing portions, to cover a bottom surface of the pouch. | 04-21-2011 |
| 20110091766 | SECONDARY BATTERY AND METHOD OF MANUFACTURING THE SAME - Disclosed are a secondary battery and a method of manufacturing the same. The method of manufacturing a secondary battery includes preparing a pouch case comprising a first case and a second case, seating an electrode assembly into the first case, covering the first case comprising a receiving part with the second case, and sealing a side portion of the first case and a side portion of the second case using a jig. The jig includes a first jig compressing the first case and a second jig compressing the second case. A first compressed width of the first case compressed by the first jig is less than a second compressed width of the second case compressed by the second jig. | 04-21-2011 |
